Question

Being 250 meters apart, two puppies started running towards each other at the same time. The first puppy ran 1.5 meter per second, while the second one ran 2.5 meters per second. What was the distance between them in half a minute?

Answer 1

Answer:

Distance between both the puppies after half minute will be 130 meters.

Step-by-step explanation:

speed of the first puppy = 1.5 m/s

=> distance covered by first puppy in 30 sec = 1.5 x 30 = 45 m

speed of the second puppy = 2.5 m/s

=> distance covered by 2nd puppy in 30 sec = 2.5 x 30 = 75 m

Hence total distance covered by both the puppies in half minute = 75 + 45

= 120 meters.

Hence distance between both the puppies after half minute

= 250 - 120

= 130 meters

Hence distance between both the puppies after half minute will be 130 meters.
